Data Transmission

1. The device or person initiating the data transmission.
5. The method of breaking data into packets that are routed independently (often "Packet _____").
8. The maximum amount of data that can be transferred over a network connection in a given amount of time.
9. A unique numerical label assigned to each device connected to a computer network.
15. The global system of interconnected computer networks that uses packet switching.
17. Clue: A small, manageable chunk of data sent over a network.
18. An advantage of packet switching: if one packet is lost, only that small piece needs to be resent.
19. A network device that forwards data packets between computer networks (like a traffic cop for data).
20. The delay before a transfer of data begins following an instruction for its transfer (often noticed in online gaming as "lag").

2. An advantage of packet switching: network resources are shared effectively.
3. _____ switching: an older method where a dedicated connection is established for the entire communication.
4. A network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules (can block certain packets).
5. _____ number: A number in a packet's header that helps reassemble the data in the correct order.
6. A term for when a network is overloaded with too much data traffic, like a traffic jam.
7. A set of rules governing the exchange or transmission of data between devices.
10. The U.S. research network that was a precursor to the modern internet.
11. The section of a packet used for error checking.
12. The physical path through which data travels (e.g., Wi-Fi, cable).
13. A comparison used to explain a complex idea (like comparing packets to postal letters).
14. The actual data (e.g., part of an email or video) within a packet.
16. The part of a packet that contains the source and destination addresses.
19. The device or person that the data transmission is intended for.
